BUENOS AIRES - A police officer is in intensive care after being shot in the head during an alleged fight between rival factions of Estudiantes fans, Argentine media reported security sources as saying on Wednesday.
The shooting occurred at a railway station in La Plata where fans were waiting to board a train to Quilmes on the outskirts of Buenos Aires for the match between Estudiantes and Argentinos Juniors in the Clausura championship.
At least two other people were hurt in the attack and a number of arrests were made and firearms confiscated, an official with the secretariat for security at football matches told La Nacion's website.
The shooting followed previous incidents this year of fighting in turf wars among hard core Estudiantes fans, whose team lost their match 1-0 to fall five points behind leaders Godoy Cruz.
The South American champions went down to a goal by 39-year-old former Estudiantes forward Jose Luis Calderon, who retired in November after differences with coach Alex Sabella only to be persuaded to play on for the rest of the season by Argentinos' Claudio Borghi.
On the night Real Madrid's Gonzalo Higuain scored for Argentina in their 1-0 friendly win over Germany, his brother Federico helped Godoy Cruz beat Lanus 2-1 to take the sole lead in the standings.
Godoy Cruz, a modest side from the Andean province of Mendoza, went ahead in the 36th minute through Colombian forward Jairo Castillo.
Striker Santiago Salcedo equalised in the 57th for Lanus but midfielder Carlos Sanchez scored the winner with 17 minutes remaining after Federico Higuain's shot came back off keeper Agustin Marchesin.
Godoy Cruz have 15 points from seven matches and can only be caught by Colon, who are away to title holders Banfield on Thursday.
Independiente are second, one point behind, after a 57th minute goal by striker Andres Silvera, his fifth in seven matches, gave them a 1-0 away win over Tigre.
Tigre goalkeeper Daniel Islas saved a penalty taken by Independiente forward Dario Gandin in the first half.
